REVIEW OF EXISTING MASTER PLAN

5.1 BACKGROUND/OVERVIEW In 1992, NHA and BMA were in accord to improve and renew Din Daeng Community Area lands mainly occupied by these two agencies as a redevelopment “Super Block”. During 1996 to 1997, NHA and BMA jointly studied the Super Block concept for the urban renewal of Din Daeng Community Area. The executive officer of BMA (the Deputy Governor) approved the cooperation approach of NHA and BMA, and a Working Committee was established accordingly by both agencies. In 1999, NHA worked out a preliminary master plan focusing on the renewal of Din Daeng Housing Complex, which is totally used as apartment housing for low to medium income households. In order to realize the master plan, NHA held several meetings with other agencies constituting the Working Committee including OCMLT, SRT, etc. The study called for a minimum budget of 20,000 million baht, and therefore, the participation of private investors was found to be necessary for minimizing public investment. Consequently, a reliable feasibility study by creditable consultants was required to comply with the Royal Act on Private Participation in State Affairs (B.E. 2535).The Act prescribes that if the project owner desires participation of private sector with assets exceeding five billion baht, the owner should hire a consultant to carry out a separate study following the requirements established by NESDB. After several meetings, the Working Committee decided to entrust a consultant team (Creative Development Co., A-7 Corporation, SJA. 3D Co.) to formulate a master plan to be submitted to the relevant authorities for approval. At a cabinet meeting held on 7th November 2000, the masterplan was approved with several conditions to be secured. The contents of the decision made at the cabinet meeting are presented in the box below. In essence, the cabinet approved the concept of the project, but requested further study as a condition for approval of implementation. NHA has been making efforts to comply with this requirement by

holding several workshops, consulting the existing residents who would be affected by the project, and requesting technical assistance from the Government of Japan, the result of which being that the JICA Study Team joined the study.

Cabinet Meeting Decision

1. Approval of the Master Plan for Land Development and Urban Renewal in Din Daeng Community as proposed by the Ministry of Interior.

2. Approval of the supporting fund for expenses needed for preparation for not over 793 Million baht within the period of 10 years. The 250 Million baht for initial stage shall be allocated from the budget of the fiscal year 2002 and 2003.

3. MOF, MOSTE, NESDB and the Budget Bureau were assigned to study further details, and find out the appropriate plan that conform with the related laws for investment planning, investment method, and joint-venture with the private sector including the support for construction of residential building, in order to compensate the right of old residents, removal fees during construction period, and environmental impact.

4. Study to improve the National Housing Act so that NHA can be more efficient in developing and managing the large scale communities, including the adjustment of NHA’s duty in the operation and management of residential buildings and improving environment of the congested and deteriorated communities of the low-income people. Giving NHA a full authority to operate and manage the cleaning system of each community and assigned the Ministry of Interior and NHA, to proceed the improvement of the National Housing Act as soon as possible.

5. NHA shall determine the criteria and complete the following procedures before initiating the project implementation:

5.1 Prepare a clear plan for removal, construction of building and temporary residence by considering the impact on households, schools and income sources of old residents. 5.2 Study and confirm the number of residents by making the name list and announce at each community for them to check for the correctness. 5.3 Determine the compensation for rental privilege and temporary removal fee for old residents during the project operation with fairness according to economic situation. 5.4 Determine the privilege of old residents to return to the project as first priority with rental fee lower than normal fee that will charge from new resident. The Special rental fee will consider from the average income of old residents. 5.5 Determine the area for pubic center i.e. library, community center, old age health center, nursery, sport and recreation center with appropriate ratio compared with total residents. 5.6 Determine the suitable and appropriate area for community shops in each residential building and specific area by giving the privilege to the residents in making more income with special rental fee and without liquidation. 5.7 Allocate the area in the commercial area with number of building by giving the privilege to the residents with special rental fee and without liquidation. 5.8 Study for possibility of joint venture by private sector for land development for commercial use by giving the opportunity to old residents to purchase the shares of private sector. 5.9 NHA should explain, making the understanding and conduct a-public hearing among the old residents to be used as guideline for operation according to 5.1 - 5.8 and proceed according to the comments from MOSTE, NESDB and Budget Bureau before project implement.

Final Report

5.2 OUTLINE OF EXISTING MASTER PLAN

5.2.1 Objectives/Target of Planning The consultant team carried out their study to meet the following requirements set by NHA.

(1) Objectives of the Project The objectives of the project are: • To set up a pilot project using the concept of urban renewal in cooperation with local government and other relevant agencies; • To bring component facilities up to current required standards; • To build new housing for existing residents with improved infrastructure and environment to provide quality of urban lives; • To provide new housing to accommodate other residents as a means to alleviate housing shortages within BMA; • To provide employment opportunities for community residents through reduced commuting time and to ease local traffic problems; and • To utilize the land development potential at the local level and to develop effective communication networks.

(2) Direction of Development The development of the Din Daeng Community Area was approached from three levels: 1) the district level (larger area comprising surrounding the super block); 2) the super block level (large block of area comprised of component projects); and, 3) the project level (component projects of the super block). At the district level, a traffic plan was developed to accommodate new and anticipated increased traffic loads. As Din Daeng district will have a main station in the underground rapid rail mass transit system (the ), with a park and ride facility for private cars, more traffic is expected. The local road network should be well connected to the city level system with access to the underground station. More parks, open spaces, and green areas are required to enhance the living environment.

Final Report

(3) Housing Development The plan proposed high-rise buildings for housing purpose to create more housing units and open space as summarized below.

Table 5.2: Proposed Housing Scheme in NHA Type No. of Housing Unit Remarks Type A1 (33m2) 3,019 units Housing for compensation to existing residents Type A2 (41.25m2) 4,193 units Sub-total 7,212 units Type B (41.25m2) 6,330 units Housing for new residents Total 13,542 units

At the full development, total floor area for housing would reach 1,434,080m2, or 574% in the floor area ratio against 24.81 ha (NHA portion). The area would be divided into 1) housing for existing residents (Housing A-1 and A-2) covering 51 rai (8.16 ha), and 2) housing for new dwellers (Housing B) mixed with commercial development covering the remaining 104 rai (16.64 ha). It should be noted that in the master plan, several blocks were excluded from the redevelopment scheme, as the owner/occupiers of shophouses in those blocks would have difficulty accepting to any new proposals and due to the complicated rights held by them. These blocks include Nos. 1,10, 12, 13, and 14.

5.2.3 Construction and Financial Plan

(1) Construction Phasing Plan The master plan proposed construction phasing plan is as shown in the following figure. The NHA responsibility is to be phased out into four sections and is scheduled to be executed within 10 years.

Final Report

5.2.4 Community Participation on Existing Master Plan When NHA selected the Din Daeng Community Project as a pilot project of urban redevelopment, it considered that the understanding and active participation of the residents at the beginning of the projects was essential as the project would affect a large number of residents in various ways. During and after the development of the master plan, NHA conducted three seminars in order to explain the concepts of the project, and to receive comments and opinions from stakeholders.

(1) Workshops during Master Planning The seminars were held on 8 May 1999, 26 January 2000, and 29 January 2000. The topic of the first and the third seminar was “Urban Community Redevelopment”, targeting different groups: 95 community leaders of Din Daeng 2 attended the first seminar, while 86 leaders of Din Daeng 1 participated in the third seminar. The second was a brainstorming seminar to discuss “Preparation of Projects to Develop Din Daeng Community Area”, for which the participants were composed of 200 delegates from relevant local and central government organizations. The result of the community leader seminars showed that most participants seemed to agree with the project. They pointed out that the buildings were old and might collapse. Building equipment had been in bad condition, and the living environment had become worse.

(2) Workshops after Finalization of Master Plan NHA held two more seminars attended by community leaders in late February and early March 2001 in Pattaya city. These seminars aimed to give correct information about the project because of confusion and misunderstanding that had spread during the election campaign period.

1) Provision of Up-dated Information In the seminars, community leaders expressed requests for participation in certain levels at critical points in the project implementation. The participants requested NHA to provide up-dated information on the project. Some leaders and local politicians suggested that NHA should conduct public

5-11 The Study for Urban Redevelopment Plan and Case Study in the Bangkok Metropolitan Area in the Kingdom of Thailand

Final Report campaigns through various means. The suggestions of these groups on the methods of the public relation campaigns included: • distributing leaflets to all flat households; • holding a seminar with more attendants (10% of residents in each flat); • arranging public meetings for each flat, in which all residents can participate and can directly ask about details of the project from NHA staff; and • setting up an information center in the project area.

2) Positive Cooperation with Community Leaders Attending community leaders expressed their willingness to assist NHA to distribute information to the residents. For example, if NHA holds a public meeting, they would participate and help explain and answer questions raised by the residents.

3) Contribution to Planning They wanted to share and provide ideas to the master plan. To this end, they suggested that NHA set up a committee, sub-committee, or working group in which representatives of the residents would be fully involved.

4) Closer Coordination on Relocation and Compensation Planning They requested a closer relationship with NHA for making decisions on relocation and compensation policies. To this end, they suggested that NHA appoint community representatives as members of a relocation committee.

5) Closer Discussion on Setting of New Rent They requested close discussion for making a decision on the new rental fee. They suggested that NHA should propose several alternatives and let the representatives of the residents consider the alternatives that might be acceptable to residents and feasible for implementing the project.

6.3 BUILDINGS/FACILITIES

6.3.1 NHA Housing Complex The first housing facility in Din Daeng Housing Complex was built in 1963 and has been expanded until 1999. Currently, the total number of facilities comprises 94 buildings (excluding 5 buildings for offices of the NHA, and the prawn shop of BMA in Block 1.1). These buildings are mostly old and deteriorated as ninety one buildings (97%) were built more than 20 years ago. Fifty six buildings (60%) are more than 30 years after construction. Focusing on housing units, those old comprise 8,390 (93%) for 20 years and over, and 3,736 (41%) for 30 years and over. As mentioned earlier, buildings in Blocks 1.10, 1.12, 1.13, and 1.14 have 230 shophouses in total. All the facilities are built of reinforced concrete structure (RC) and most of them are five stories with some exceptions, including the highest of 14 stories, built during 1997 – 1999. Typical floor plan of the buildings constructed before 1977 is the single corridor type and that of later buildings is twin corridor type. The following table shows an outline of the housing facilities:

Regarding the housing units, the majority are used as rental flats, excluding Block 1.13 which is hire-purchased. Floor area of these units range from 31m2 to 54m2 with the average of 40.54m2. The floor area per unit is related to the year of construction as follows. Units before 1975 : floor area - around 40m2

Units after 1975 : floor area - around 35m2 and more than 50m2 (Block 1.13 and 1.14) Most of the units are single room type except those having three bedrooms located in Blocks 1.12 and 1.13. A single room type has an open room (or a large balcony), which serves for various purposes including cooking and dinning. Each of these units originally had a toilet and a shower room, but no kitchen. Composition of unit plan types in Din Daeng Housing Complex is summarized in the following figures and tables.

(2) Water Supply System Figure 6.5 shows layout of existing water distribution pipelines. Drinking water is supplied from trunk distribution pipelines with a diameter of 300 mm. Enclosing the northern part of Asok-Din Daeng Road, these pipelines are connected with transmission pipelines of 600 mm and 1,200 mm at three points. Distribution for inner parts from 300 mm pipelines is taken by pipes with a diameter between 150 mm and 200 mm. Apart from those mentioned above, drinking water for Block E and Block A in the southern part of Asok-Din Daeng Road is directly supplied by 200 mm and 300 mm distribution pipelines.

(3) Sewage Treatment System There is no central waste water treatment plant under operation to cover the DC Area. All building facilities therefore are equipped with individual treatment systems in accordance with regulations. Regarding the housing section, each building has a septic tank (community plant) with a capacity of 1,000 m3/day operated by NHA. The Department of Drainage and Sewerage (DDS), BMA is constructing Din Daeng central sewage treatment plant, which is designed to process 341,000 m3/day for 697,000 population in Phase 1 and 463,000 m3/day for 1,080,000 population in Phase 2. The plant will cover the entire DC Area by the combined system as presented in Part II of this report. The plant is scheduled to start operation in a few years.

(4) Rainfall Drainage System DC Area is divided into two catchment basins: the eastern part and western part of Pracha Songkhro Road. Storm water in the western part is pumped out by pumps with capacity of 6 m3/s at Block 2.8 after collecting through drainage pipes of 800 mm diameter. The western part is drained by culvert of 1,500mm along Asok-Din Daeng Road, as shown in Figure 6-6.According to DDS, the inundation areas in DC Area are pointed out at Pracha Songkhro Road and Block B.
